An alternative, at least on unix, is to make (make-pathname :directory
'(:relative)) print as #p".". Currently #p"." is read as a pathname
with name ".", but if we change that to return a directory, then we're
ok. But of course, we would then lose for (make-pathname :name "."),
but there isn't really a unix file with name "."; it's a directory.
I hate this stuff.
